Piper auritum (Kunth) Fungal Endophytes: A Source of Metabolites to Inhibit the Formation of Advanced Glycation End Products

open access: yesChemistry &Biodiversity, EarlyView.
Endophytic fungi of P. auritum were evaluated for their ability to produce inhibitors of formation of advanced glycation end products (AGEs). Neopestalotiopsis sp. H2 and Diaporthe sp. H5 extracts were the most active. So, we performed their chemical profiling by untargeted and phenolics‐targeted metabolomic approaches to identify the potential ...

Towards the Use of Metabolic Volatiles in Breath for Determining Drug Response: Gstachamine as an Unlabeled Substrate to Measure CYP3A4 Activity

open access: yesChemMedChem, EarlyView.
A potential substrate, gstachamine, was engineered for a future CYP3A4 assay. HepG2 cell clones overexpressing CYP3A4 were used to investigate both liquid and headspace phases after incubation. A specific N‐dealkylated metabolite and butanone were detected using LC‐MS and PTR‐ToF‐MS, respectively.

C1′‐Branched Acyclic Nucleoside Phosphonates as Inhibitors of Plasmodium Falciparum 6‐Oxopurine Phosphoribosyltransferase

open access: yesChemMedChem, EarlyView.
Novel C1'‐branched acyclic nucleoside phosphonates were synthesized. The compounds are inhibitors of Plasmodium falciparum and human 6‐oxopurine phosphoribosyltransferases with Ki values as low as 0.4 µM and 0.7 µM, respectively. A phosphonodiamidate prodrug exhibited IC50 = 4.3 µM against a drug‐sensitive strain of P.

Safety and Efficacy of the NMDA‐2b‐Selective Negative Allosteric Modulator BI 1569912: A Phase Ib Randomized Trial in Major Depressive Disorder

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Selective N‐methyl‐D‐aspartate receptor subunit 2b negative allosteric modulators (NR2B NAMs) are being explored as potential new treatment options for major depressive disorder (MDD). This Phase Ib, randomized, double‐blind, placebo‐controlled, parallel‐group trial was conducted in adults (N = 59) with moderate‐to‐severe MDD and insufficient response ...

The pulmonary artery pulsatility index in patients with severe aortic stenosis undergoing valve replacement

open access: yesESC Heart Failure, EarlyView.
Abstract Background and aims The pulmonary artery pulsatility index (PAPi), that is, the pulmonary artery pulse pressure (PAPP) divided by the mean right atrial pressure (mRAP), is an increasingly used invasive index of right ventricular function. We sought to assess the prognostic impact of the PAPi in unselected patients with aortic stenosis (AS ...

A simplified approach for diagnosing heart failure with preserved ejection fraction by assessing the left atrium and natriuretic peptides

open access: yesEuropean Journal of Heart Failure, EarlyView.
Applying a simplified left atrial/natriuretic peptide (LA/NP) approach by combining enlarged LA volume indexed for height2 or elevated (N‐terminal pro) B‐type natriuretic peptide [(NT‐pro)BNP], using different cut‐off values for sinus rhythm (SR) and atrial fibrillation (AF) history.
